Timer that activates Random(); run again without delaying Switch, help

Shadowx180

So I merged a timer with a random the best i could and came up with this idea. It works as expected timer every second causes a int to change and activates a case to print a word. I want it to activate a switch and continue to repeat over and over until random is changed again and activating another switch case.

int initialTime;
int interval = 1000;

void setup()
{
  initialTime = millis();
}

void draw()
{
   String[] num = { "0", "1", "2","3"};

  // if current time minus lastStored bigger than interval 
  if (millis() - initialTime > interval){

      int index = int(random(num.length));  // Same as int(random(4))
          // reset counter
    initialTime = millis();
        switch(index) 
              {
              case 0: 
                println("Zero");  // Does not execute
                break;
              case 1: 
                println("One");  // Prints "One"
                break;
                  case 2: 
                println("two");  // Prints "two"
                break;
                  case 3: 
                println("three");  // Prints "three"
                break;
              }

  }
}

The switch should be outside the timer i think, look, is that so?

int initialTime;
int interval = 1000;
int index ;

void setup(){
  index = int(random(4));
  initialTime = millis();

}

void draw(){


  // if current time minus lastStored bigger than interval 
  if (millis() - initialTime > interval) {

    index = int(random(4));  // As num was unused... 
    // reset counter
    initialTime = millis();
    println("one sec passed... new index is: " + index);
  }
  switch(index) 
  {
  case 0: 
    println("Zero");  // Does not execute
    break;
  case 1: 
    println("One");  // Prints "One"
    break;
  case 2: 
    println("two");  // Prints "two"
    break;
  case 3: 
    println("three");  // Prints "three"
    break;
  }
}

Can't figure out what you want to. But I guess if you wanna the switch to continue repeating,
you should place it outside the if block!

Thank You _vk I didn't think of using "index = int(4);" in setup. I was trying outside of the if and int index on top and so forth and I could never get it to work and so my overall project progresses to nearly being completed after i integrated this example into it.

ops, was meant to be index = int(random(4)); corrected above ; )
